Faster access time(uses data bus directly and not through any controller) and no moving parts
Optical disk storage offers several advantages over magnetic disk storage, including greater durability and resistance to environmental factors such as dust and magnetic fields. Additionally, optical disks typically have a longer shelf life, making them suitable for archival purposes. They also tend to consume less power during operation and are often lighter and more portable than magnetic disks. However, optical disks generally have slower read/write speeds compared to magnetic disks.
A hard disk drive is a type of magnetic storage device. A magnetic storage device stores data on a magnetized medium. Other types of magnetic storage includes magnetic recording tapes and the stripes on credit cards.

Hard Disk
Magnetic storage is used on hard drives and floppy disks. Sectors of the disk are charged magnetically and are easily changed later. Optical storage uses a laser to read data. On a cd/dvd, the laser picks up tiny marks made starting in the center and rotating outward.
Floppy disks use magnetic disk to store the data.
A floppy disk is an old type of removable, computer memory storage.
Yes both are secondary storage devices. Primary storage devices include RAM & ROM. Secondary storage devices include magnetic disks like hard disks and cds(optical disks)
